The more rabidly anti-gay and "Christian" a commenter considers himself, the higher the likelihood that he or she will resort to describing vulgar sexual acts supposedly performed by GLBT people in an attempt to vilify them. Usually affirmed when an actual GLBT person is grossed out by the rhetoric.
Named for Peter ("Porno Pete") LaBarbera, founder of Americans for Truth About
Homosexuality, a "Christian" organization whose sole purpose is to oppose every measure that might lead to GLBT people being considered
human beings. LaBarbera lends his name to this law specifically through his "hobby" of attending leather and BDSM conventions, camera in hand, for "research purposes", and also because he mentions corprophilia at every
opportunity.
